"Microsoft needs to release another version of XP [with Bluetooth support] at the same time that the CE version, including the [CE] hardware, will hit the market," Wu said. "If you look at Microsoft's history, they do have a release of an [operating system] update [between] nine to 12 months after the first release, historically."
Microsoft declined to comment.
The decision by Microsoft not to support Bluetooth in Windows XP clears the way for immediate action by third-party Bluetooth vendors such as San Francisco-based Rappore Technologies.
"It is very typical for [an early technology] that the more nimble, smaller companies can support it faster," said Ken Ebert, a senior engineer at Rappore, which he co-founded. "We can support and deploy Bluetooth right now."
Microsoft expressed equal concern for the support of USB 2.0 in Windows XP, possibly opting to support Apple Computer's FireWire as its connecttion for high-speed peripherals such as video camcorders. USB 2.0, with its development near completion, is a next-generation USB connection.
